| 11 |

% |
| 12 |
|
|
%other inputs: file_name, file_characteristics, depth (1D vector), prof_descr (texte) |
| 13 |
|
|
% file_characteristics(1)=total number of profiles |
| 14 |
|
|
% file_characteristics(2)=last profile written |
| 15 |
|
|
% if file_characteristics(2)==0 we create the file |
| 16 |
|
|
% file_characteristics(3)=length of the character description |
| 17 |
|
|
% file_characteristics(4)=missing_value |
| 18 |

|
|
%asumptions about the inputs: |
| 20 |
|
|
% T is potential temperature, we do not use the missing value |
| 21 |
|
|
% but 0 for weight/mask (facilitate "cost" computation), |
| 22 |
|
|
% units are the standard ones (see the netcdf attributes) |
| 23 |
|
|
% |
| 24 |
|
|
%usage: see netcdf_postprocess_argoctd.m, netcdf_ecco_recompose.m |

%Gael, June 7th 1007: I add the option to write interpolation information |

% assumption: varargin is mystructInterp (i,j,weights), while |
| 28 |

% XC11 etc. have been added to mystruct1D |
| 29 |
|
|
%Left for later: genericity (read/compute dim4mygrid), additional info about interp stuff |
